The hitch receiver is there, but they have a proprietary "Z" hitch that hangs down (the reference above to the hitch failing under too much load). With the Curt the tongue weight went way up ... how much ... I cannot say at this time, but it did indeed go up.
Also, if you buy a used truck and it doesn't have the proprietary hitch dongle, that piece is over $500 (even used) approaching $700 new. (last time I checked).
and on the truck:
And the Curt hitch is about $150.00 not including installation.
